I definitely need to do this with a lot of music. Even if I enjoy it without playing, I'll enjoy music from games I have played so much more. VGM's as much a visual experience as it is an auditory experience, at least for me. I like to have some sort of context to imagine while the song's playing.
There's some games that have such incredible music that I'm just awestruck by it and I've never even played them. Makes me wonder how much more I'd enjoy it if I ever get around to playing them =/.
Ganon's final boss theme from OOT isn't anywhere so meaningful unless you've got that sense of epic doom from actually playing the game

. Terra's theme not quite so grand unless you've got the emotions experienced from literally over that entire game.
Jam it back in, in the dark.
